Microarray experiments help scientists to study the expression level of thousands of
genes simultaneously. These experiments have many design challenges, such as, for example, which
mRNA samples should be co-hybridized ...

The reality of rape as a direct form of contact crime remains deeply entrenched in South African communities, despite numerous efforts from various governmental stakeholders to curb this heinous crime. The Criminal Law ...

This paper paves the way when the assumption of normality is challenged within the
wireless communications systems arena. Innovative results pertaining to the distributions of quadratic forms and their associated eigenvalue ...

Consistent associations have been found between advanced paternal age and an increased
risk of psychiatric disorders, such as schizophrenia in their offspring. This increase appears
to be linear as paternal age increases. ...

High levels of crime in South Africa and the
resulting court cases requiring bite mark evidence have necessitated
continuous research into the prevalence and interrelationship
of recognisable dental features present in ...

BACKGROUND : Anterior cruciate ligament (ACL) injuries are common among athletes and the general public. These injuries may lead to significant absence from all activities with associated financial and social burdens for ...

The exponential distribution is a popular model both in practice and in theoretical work. As a result, a multitude of tests based on varied characterisations have been developed for testing the hypothesis that observed ...

If not managed properly, the cost of South African municipal infrastructure
projects could represent a major financial burden on the country’s fiscus. Cost
management on these projects is, therefore, a significant parameter ...

In a country notorious for violent crime, it seems that South African medico-legal laboratories make
minimal application of technology in the death investigation process and little attention is given to trace
evidence. ...

OBJECTIVE: The auditory steady-state response (ASSR) to air-conduction (AC) stimuli has been widely incorporated into audiological test-batteries for the pediatric
population. The current understanding of ASSR to bone ...

Bayes analysis of the normal model has been
thoroughly investigated by numerous statisticians and reported in the literature. The explicit
form of the Bayes estimators under LINEX loss will be derived, which has not been ...

Based on a type II censored sample, Bayesian estimation for the scale parameter of the
Rayleigh model is carried out under the assumption of the squared error loss function. A generalised
hypergeometric distribution with ...

The estimation of a location parameter of the normal distribution has been widely discussed and
applied in various situations. The Bayes estimators under Linear Exponential (LINEX) loss are
functions of the moment ...

The traditional (frequentist) tr -chart is a Shewhart-type chart useful for monitoring times between events
(interarrival times) following an exponential distribution. This problem often arises in high-yield processes
where ...

Real phenomena often leads to challenges in data. One of these is outliers or influential values. Especially in a small sample, these values can have a major influence on the modeling process. In the beta regression ...

In this paper we propose the beta slashed generalised half-normal distribution, which
includes some important distributions such as the half-normal, slashed half-normal and generalised
slashed half-normal distributions. ...

In this article, the bimatrix variate beta Type IV distribution is derived from
independent Wishart distributed matrix variables. We explore specific properties of
this distribution which is then used to derive the exact ...

In this article, a bivariate generalisation of the gamma distribution is proposed
by using an unsymmetrical bivariate characteristic function; an extension to the
non central case also receives attention. The probability ...
